How to set value from md-options on controller? - angularjs

I have a simple md-select component. I want to set the value of number.number on the vm.telephonyInfo.phone.number property in the controller.
<md-input-container>
<md-select ng-model="vm.telephonyInfo.phone.number" placeholder="Selecteer een nummer" required>
<md-option ng-repeat="number in vm.phonenumbers"
ng-value="{{number.number}}" ng-click="vm.login()">{{number.number}}</md-option>
</md-select>
</md-input-container>
When I select a option I log the login() function but the property this.telephonyInfo.phone.number always is null.
Is my data-binding wrong? I thought I had to put the ng-value in the md-option and the ng-model in the md-select.

Use the ng-change directive instead of ng-click:
<md-input-container>
<md-select ng-model="vm.telephonyInfo.phone.number"
ng-change="vm.login()"
placeholder="Selecteer een nummer" required>
<md-option ng-repeat="number in vm.phonenumbers"
̶n̶g̶-̶v̶a̶l̶u̶e̶=̶"̶{̶{̶n̶u̶m̶b̶e̶r̶.̶n̶u̶m̶b̶e̶r̶}̶}̶"̶
ng-value="number.number"
̶n̶g̶-̶c̶l̶i̶c̶k̶=̶"̶v̶m̶.̶l̶o̶g̶i̶n̶(̶)̶"̶ >{{number.number}}</md-option>
</md-select>
</md-input-container>
Also avoid using double curly {{ }} interpolation in ng-value directives. See AngularJS Developer Guide - Why mixing interpolation and expressions is bad practice.

AngularJS Material: Cannot get value of md-select

I've got a AngularJS Material Select:
<md-input-container style="margin-right: 10px;">
<label>Roll</label>
<md-select id="acc-type" required="" ng-model="rolle">
<md-option ng-selected="true" value="Tenant">Tenant</md-option>
<md-option value="Lessor">Lessor</md-option>
</md-select>
</md-input-container>
and I want to get the actual selected option. I tried it with
var e = document.getElementById("acc-type");
var selectedItem = e.value;
but all I receive is undefined. Is there any option to get the value of a md-select in AngularJS?
Since you have already defined ng-model="rolle" in your md-select, you can access it via $scope.rolle
Try:
var selectedItem = $scope.rolle
Its in angular Js and model is already assigned so try
Try
console.log($scope.rolle);

How to add title for selected value in md-select?

I am having md-select like :
<md-select ng-model="someModel" title={{someModel}}>
<md-option ng-value="opt.id" ng-repeat="opt in neighborhoods2">{{ opt.name }}</md-option>
It shows opt.id value in title.But I have to show opt.name in title.How to add a title attribute for the selected value's name?
for that you have to select object in ng-value like
<md-select ng-model="someModel" title={{someModel.name}}>
<md-option ng-value="opt" ng-repeat="opt in neighborhoods2">{{ opt.name }}</md-option>
</md-select>
but make sure in your controller you will get an object so you have to get id as
if(angular.isString(someModel)){
var myValue= JSON.parse(someModel).id;
}
Instead of setting the value to opt.name, you could use the opt object itself as the value. That way, your md-select model will have the name and id of whatever item is selected.

md-virtual-repeat not working wiht md-select

I'm trying to implement md-virtual-repeat for md-select which has more than 2000 items to select. This not working with the md-option.
<md-input-container>
<md-select ng-model="break.start_time" md-on-open="vm.mdSelectOnOpen()">
<md-virtual-repeat-container id="vertical-container">
<md-option md-virtual-repeat="option in vm.time" value="option.value" >{{option.text}}</md-option>
</md-virtual-repeat-container>
</md-select>
</md-input-container>
What is the problem with this? I have updated a plunker with my problem. see
Updated Answer
Since you are using md-virtual select the check boxes you can refer the below codepen, there was no need to add a check box itself since md-select has an attribute called multiple which will add the check boxes
Code
<md-input-container>
<label>Select an option</label>
<md-select ng-model="selectedOption" md-on-open="mdSelectOnOpen()" multiple>
<md-virtual-repeat-container id="vertical-container">
<md-option md-virtual-repeat="option in options" ng-value="option" ng-selected="selectedOption.indexOf(option) > -1">{{option}}</md-option>
</md-virtual-repeat-container>
</md-select>
</md-input-container>
Codepen: here
Old Answer
You need to give ng-selected option and ng-value.
<md-input-container>
<md-select ng-model="break.start_time" md-on-open="vm.mdSelectOnOpen()">
<md-virtual-repeat-container id="vertical-container">
<md-option md-virtual-repeat="option in vm.time" ng-value="option.value" ng-selected="break.start_time==option.value">{{option.text}}</md-option>
</md-virtual-repeat-container>
</md-select>
</md-input-container>
Refer: codepen
I know this is an old thread, but maybe this can help to someone.
If the following did not work
$scope.$broadcast("$md-resize")
use this instead:
angular.element(window).triggerHandler('resize')

Get data from md-select

I am using Angular Material to make my new web app, I want to get the selected value from an <md-select> and the problem is that I am new to angularjs and how it works. If anyone could help me, it would be really appreciated.
HTML :
<md-input-container>
<label>Rating</label>
<md-select ng-model="userRating">
<md-option><em>None</em>
</md-option>
<md-option ng-repeat="rate in ratings" ng-value="rate.abbrev">
{{rate.abbrev}}
</md-option>
</md-select>
</md-input-container>
You can just get the value by using the $scope variable
In controller
console.log($scope.userRating);
Inorder to get the selected value on change , you can pass the selected to a function and display,
<md-select ng-change="Print()" class="inline-flex md-select-down" placeholder="Select" ng-model="model">
<md-option ng-repeat="item in ratings" value="{{item.value}}">
{{item.abbrev}}
</md-option>
</md-select>
Controller:
$scope.Print = function(){
alert($scope.model);
}

md-select not binding to the object referenced by ng-model

I have a form with some md-select dropdowns which im trying to bind with a scope object in my angular controller.
The html looks like that :
<div id="horizontal_form_category" class="row">
<div class="col-md-2 col-lg-2" data-ng-repeat="r in categories[general]" dir="rtl">
<md-input-container>
<label> {{ r.name }} </label>
<md-select ng-model="formObject[r.name]" class="md-no-underline">
<md-option ng-repeat="option in r.values" ng-value="option "> {{ option }} </md-option>
</md-select>
</md-input-container>
</div>
</div>
The controller has a definition of the object $scope.formObject = {}; (Although it should work without it)
But, unfortunately, the $scope.formObject object in my controller stays empty.
Any ideas what could cause such weird behavior ? I have some normal bootstrap components whom ng-model is written the same and are working just fine.
Thanks
Does this help in any way? - CodePen
The true as the last parameter for $watch checks for changes in the object formObject.
Markup
<div ng-controller="AppCtrl" ng-cloak="" ng-app="MyApp">
<md-input-container>
<label> Options </label>
<md-select ng-model="formObject['Options']" class="md-no-underline">
<md-option ng-repeat="option in options" ng-value="option "> {{ option }} </md-option>
</md-select>
</md-input-container>
</div>
JS
angular.module('MyApp',['ngMaterial'])
.controller('AppCtrl', function($scope) {
$scope.options = ["Earth", "Saturn", "Jupiter"];
$scope.$watch("formObject", function () {
console.log($scope.formObject);
}, true)
});
Apparently there wasnt any bug.
My form's md-select were empty and therefore the formObject was empty.
The minute I started puting values, the formObject got filled, one field at a time, containing only the fields that were set.
I added a default value and everything is now showing correctly, just to be sure this was the "bug".
In retrospect, this bevahiour actually saves me some lines of code so I adopted it :)
Gotta thank #camden_kid answer for the $watch tip, helped me figure it out in matter of seconds.
